HMS ALACRITY OFF GIBRALTAR

HMS Alacrity was commissioned on 2 July 1977.

During the Falklands war,  Alacrity sank the Argentine supply ship ARA Isla de los Estados by gunfire on the night of 10–11 May 1982, near Swan Islands. At the time, Alacrity was on a mission to establish whether or not the Argentines had mined the north entrance to Falkland Sound. 

As Alacrity left Falkland Sound on 11 May, the Argentine submarine, San Luis was reported to have fired two torpedoes at Alacrity and her sister ship HMS Arrow. Both missed, and the ships rejoined the task force.

In 1989, whilst deployed as West Indies Guard Ship, she was tasked for humanitarian relief on the island of Montserrat in the British West Indies after the island suffered devastation in the wake of hurricane "Hugo". The ship's Lynx helicopter was the sole means of transporting aid ashore as the port was destroyed.

Alacrity was decommissioned and transferred to Pakistan on 1 March 1994
